5. Discussão dos Resultados
5.3. Limitações e sugestões para pesquisas futuras
Esta investigação teve algumas limitações, como a impossibilidade de reunir um grupo único, para que assim pudesse ser dividido em dois grupos, nas mesmas condições e no mesmo sítio. O facto de os dois grupos terem sido reunidos em ambientes, momentos e situações diversas, foi um aspeto dificultador.
O tamanho da amostra pode ser considerado uma limitação, uma vez que não foi possível recrutar um número maior de participantes.
Não se deve descartar um possível viés, pelo fato de que o Grupo Experimental foi expressivamente formado por crianças pertencentes a uma alta classe social, consequentemente com acesso à educação de melhor qualidade, recursos tecnológicos e de informação e que vivem em zonas nobres do espaço urbano. Isto de alguma forma pode ter influenciado nas respostas e no comportamento durante a realização do experimento, uma vez que o outro grupo foi formado por crianças de diferentes perfis e que estavam na presença da mãe, do pai ou de ambos. Tais características foram percebidas por meio de observação direta da investigadora.
Os diferentes ambientes onde o experimento foi realizado, podem ter implicado em algum viés, pois há a possibilidade de as crianças terem sofrido alguma distração externa, apesar de todos os cuidados para que isto fosse eliminado.
Como sugestão para pesquisas futuras, seria interessante que fossem avaliados os efeitos à longo prazo da exposição à conteúdos do Youtube relacionados aos alimentos
57 saudáveis, de modo que o experimento seja aplicado mais de uma vez, ao longo de um período e com a utilização de um maior número de conteúdos em vídeo. Uma abrangência maior de faixa etária e classes sociais seria enriquecedora. A metodologia a ser utilizada poderia ser combinada com ferramentas de análise qualitativa, para que sejam medidos e analisados outros aspetos, minimizar os vieses e obter resultados mais precisos e consistentes. Equiparar o desenho do experimento ao realizado por Dias & Agante (2011), que comparou dois grupos, onde um foi exposto a alimentos saudáveis e o outro a não saudáveis, poderá gerar resultados mais claros.
Seria enriquecedor se fossem avaliados mais a fundo o aspecto da classificação do IMC das crianças, a medir se este é um fator que influencia ou não as atitudes e escolhas.
Outra sugestão seria o desenvolvimento de pesquisas de cunho neurológico, que medissem as ativações cerebrais quando da exposição a alimentos saudáveis, não só para com jovens, mas também direcionada a adultos, como sugere Folkvord & Bruijne (2020).
Por fim, o objetivo primordial desta pesquisa é reforçar a conscientização de que os conteúdos voltados para o público infantil devem focar na saúde e bem-estar das crianças e adolescentes, através da promoção de temas que exerçam efeito positivo na infância e adolescência. É importante ter a consciência de que conteúdos digitais com alimentos saudáveis podem não vir a ser um fator primordial para a melhoria na alimentação das crianças e jovens e nem para a diminuição da obesidade infantil, no entanto é dever dos pesquisadores desenvolver ferramentas para que as crianças sejam cada vez menos prejudicadas nos ambientes digitais.
